# Cheersheet

> Load your team's cheer mix in the browser, tap the first 1, get a beat grid in 8-counts, write the count sheet, print it and practise at a slower speed.

The music is your team's own. Cheersheet reads the file you choose on this device and never sends it anywhere. Cheersheet is not affiliated with any cheer or dance governing body, competition producer, event brand or music company.

## How it works

1. Load the mix (MP3, M4A or WAV). The browser decodes it on the device; nothing is uploaded.
2. Tap the first "1". Onset detection finds the pulse, a tempo guard keeps it in the expected range (half and double tempo are one click apart), and the beats are fitted to a grid of tempo segments. Tempo anchors can be dropped on any 8-count, and rows that drift off the music are flagged.
3. Write the count sheet: one row per 8-count, a short cue on any count, sections (stunt, tumbling, jumps, dance, pyramid, transition) with names and colours, and formation dots per 8-count.
4. Practise: play the mix at 50 to 100 percent speed with pitch kept, with spoken or clicked counts, section jumps and loops, and a projector view of the running count.
5. Print the count sheet (landscape, one 8-count per row, sections shaded) and athlete cue cards; export CSV, the project file, or a WAV practice track of clicks over the mix at the chosen speed.

## Beat grid on test tracks

Synthetic tracks with known beat times, run through the same code when this file was built (tempo ranges: cheer 120 to 170 BPM, dance 85 to 150):

- Steady 144 BPM, kick on every beat: strongest pulse 144 BPM, grid 144 BPM, mean error 1.3 ms.
- 144 BPM for 8 eights, then 152 BPM: strongest pulse 76 BPM, grid 144 then 152 BPM, mean error 1.3 ms.
- 144 BPM with a half time kick and backbeat: strongest pulse 72 BPM, grid 144 BPM, mean error 0.8 ms.
- 150 BPM, hits spread by up to 8 ms, more noise: strongest pulse 75 BPM, grid 150 BPM, mean error 1.8 ms.
